[ Upstream commitb135e324d7] The AIP code signals the phys_mtu in the following query_port() fragment: props->phys_mtu = HFI1_CAP_IS_KSET(AIP) ? hfi1_max_mtu : ib_mtu_enum_to_int(props->max_mtu); Using the largest MTU possible should not depend on AIP. Fix by unconditionally using the hfi1_max_mtu value. Fixes:6d72344cf6("IB/ipoib: Increase ipoib Datagram mode MTU's upper limit") Link: https://lore.kernel.org/r/1644348309-174874-1-git-send-email-mike.marciniszyn@cornelisnetworks.com Reviewed-by: Dennis Dalessandro <dennis.dalessandro@cornelisnetworks.com> Signed-off-by: Mike Marciniszyn <mike.marciniszyn@cornelisnetworks.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
